1. An ultrasonic instrument comprising:
(a) a body;
(b) a shaft assembly extending distally from the body;
(c) an ultrasonic blade positioned distal to the shaft assembly;
(d) a pivoting member comprising a clamp arm, wherein the pivoting member is pivotably coupled with the shaft assembly about a pivot axis, wherein the clamp arm is pivotable with respect to the ultrasonic blade from an open position to a closed position to thereby clamp tissue between the pivoting member and the ultrasonic blade; and
(e) a guide feature comprising a tapered projection configured to laterally align the clamp arm relative to the ultrasonic blade as the clamp arm is pivoted toward the ultrasonic blade; wherein the tapered projection is configured to laterally align the clamp arm relative to the ultrasonic blade with a progressively increasing force as the clamp arm is pivoted toward the ultrasonic blade.
